lead. STAND & HOOK-UP This meter can be used in any operating position. It has an oblique bracket and a hook behind it. Users should choose according to their own needs. And it have magnets on its back to absorb the suspension. OPERATING INSTRUCTIONS CAUTION! When making voltage or current measurements, develop the habit of turning off...
OPERATION PROCEDURES DC Voltage Measurement WARNING: USE EXTREME CARE WHEN MAKING MEASUREMENTS FOR HIGH VOLTAGE. DO NOT TOUCH TERMINAL OR PROBE ENDS. 1. Set the selector switch to the appropriate DCV range to be used. 2. Connect the BLACK test lead to the “-COM” jack and the RED test lead to the “+”...
2. Connect the BLACK test lead to the “-COM” jack and the RED test lead to the Red “+” jack for Current at/less than 0.5A. For large current max. 10A, move the red test lead to the Red “10A” jack. 3.
3. Read the linear (forward voltage) VF of the diode on the LV scale. Continuity Test WARNING: DO NOT APPLY VOLTAGE TO MEASURING TERMINAL WHILE RANGE SWITCH IS IN OHM POSITION. Set the selector switch to the BUZZ range. Connect the test leads to two points of circuit.
scale. 4. For more dB scope, change the selector switch to the others of ACV ranges and make the same actions. Add the appropriate number of dB scale reading as noted on the chart below. NOTE: For absolute dB measurements, circuit impedance must be 600 Ohm. 0 dB = 1mw dissipated in a 600 Ohm impedance (equivalent to 0.755V across 600 Ohm) ACV RANGE...
